Huawei quidway s7700 - Binding the GRE Tunnel with the VPN to Which CE Belongs on PE

tunnel-protocol gre
The tunnel is encapsulated as a GRE tunnel.
Step 4 Run:
source { source-ip-address | interface-type interface-number }
The source address or source interface of the tunnel interface is configured.
NOTE
The virtual IP address of the VRRP backup group can be configured as the source address of the GRE
tunnel.
The source interface of the tunnel cannot be the interface of the tunnel, but can be specified as
the interface of another tunnel.
The source address of the tunnel specified on the PE is identical with the destination address of
the tunnel specified on the CE. The destination address of the tunnel specified on the PE is
identical with the source address of the tunnel specified on the CE.
Step 5 Run:
destination [ vpn-instance vpn-instance-name ] ip-address
The destination address of the tunnel interface is configured.
If the tunnel passes through another VPN, the parameter vpn-instance vpn-instance-name need
to be specified. If the tunnel passes through the public network, the parameter is not required.
Step 6 (Optional) Run:
mtu mtu
The MTU of the interface is modified. The new MTU takes effect only after you run the
shutdown and the undo shutdown commands in succession on the interface.
Step 7 Choose one of the following commands to configure the IP address of the tunnel interface.
l Run the ip address ip-address { mask | mask-length } [ sub ] command to configure the IP
address of the tunnel interface.
l Run the ip address unnumbered interface interface-type interface-number command to
configure IP unnumbered for the tunnel interface.
